CAR-VVHEEL.

SPECIFICATICN forming part of Letters Patent No. 584,806, dated June 22, 189'?.

Application filed July 2, 1896.

To all whom t may cm2/cera.-

Be it known that I, JAMES S. Wooncocn, a citizen of the United States, residing at New Lexington, in the county of Perry and State of Ohio, have invented a certain new and useful Improvement in Oar-Viheels, of Which the following is a speciiication.

My invention relates to the improvement of car-Wheels, and has particular relation to an improved construction of Wheels for minecars.

My invention consists in certain improvements in the construction and arrangement of parts, which will be more fully pointed ont hereinafter. These improvements are illustrated in the accompanying drawings, in Which- Figure l represents a face view of one of my improved Wheels, showing a portion of the hub-cap broken away. Fig. 2 is a view of the outside thereof. Fig. 3 is a view in elevation at right angles with those shown in Figs. l and 2. Fig. e is an inner face vien7 of the hub-cap. Fig. 5 is an enlarged central sectional vieW of the central portion of said Wheel, and Fig. 6 is a central vertical section of thev hub portions of my improved Wheel With other parts omitted.

Similar letters refer to similar parts throughout the several views. i

c represents the body of my improved Wheel, Which is preferably of the open form shown, although it is evident that the same may be formed solid and thereby dispense with the spokes. In the construction of my improved Wheel I provide a hub consisting of an inner cylindrical portion l) and an outer cylindrical portion c, these hub portions being connected near their outer ends by short radial spokes or pins c2. Between the hub portions e and ZJ is formed an oil-chamber c.

In the inner end of the hub portion l) and on the inner side" thereof I provide an inner surface-recess d, which communicates at desirable intervals with the inner end portion oi' theoil-chamber c' through the medium of openings d.

e represents a cylindrical bearing-sleeve which is adapted to ht and rotate Within the hub portion l). The inner end of this bear- Serial No. 597,887. (No model.)

ing-sleeve is flush with the inner end of the hub portion c, said sleeve thereby passing the recess CZ, While the outer end of said sleeve is provided with a peripheral flange or shoulder e', Which abuts against the outer end of the hub portion b. On the outer side of this iiange said sleeve is adapted to be detachably connected with the outer end of the axle f, Which passes through said sleeve. The means employed for this connection consist inthe insertion of a pin j" through oppositely-located pin-openings formed in the corresponding ends of the sleeve and axle, as shown more clearly in Fig. 5 of the drawings.

g represents ahub-cap which, as indicated in the drawings, is in the form of a cup-shaped body provided on its periphery with a continuous flange g', the latter having` its inner face recessed to partially receive the outer end of the external hub portion c. Vithin this flange-recess, which is indicated at g2, and between said flange and the outer end of the hub portion c I provide a Washer or packing-ring h. The cap thus constructed has. its iiange portion g provided at desirable intervals with projecting attachin g-lu gs i, through which bolt-holes 7c are formed. 7c are adapted to receive the ends of bolts lo, which pass inward through bolt-holes formed in the inner ends of the Wheel-spokes a', While the outer ends of said bolts are adapted to receive nuts 7a2. As indicated at m, I provide the inner ed-ge of the iiange g at proper intervals with depressions or recesses Which are adapted to engage With those spokes a Which come between the spokes which receive the bolts.

As indicated in the drawings, the binderbox n, the character of which is illustrated in an application for patent executed by me and filed in the United States Patent Office July 2, 1896, and numbered serially 597,886, Which is provided with a circular bearingshoulder n' on its outer end, which is adapted to lit in the correspondingly-shaped recess in the end of the hub portion b, said binder-box abutting against the end of the sleeve c.

From the construction Which I have herein shown and described it is obvious that the oil which passes from the oil-chamber to the sleeve through the medium of the openings These holes IOO clandinternal hub-recess d may iind a lodgment in said recess, the shoulder or that portion of the hub which is between said recess and the outer end of the binder-box serving to prevent any outward iow of said oil and to prevent dust or other foreign matter entering said oil-recess orcoming into contact with the bearing-surface of the sleeve from the outside. It will be observed that this construction admits of the sleeve receiving all the bearing of the wheel. It has been common to employ at the inner end of the hub an inwardly-extending portion or shoulder which came into direct bearing-contact with the axle, but the necessity of employing this shoulder portion has been obviated by the introduction of the internal recess d, which is employed for the purposes hereinbefore set forth. In this manner I not only obtain a more perfect and uniform bearing for the wheel, but by confining said bearing entirely to the sleeve it is obvious that all wear is taken from the aXle and that I am enabled to conne the bearing of the hub to one kind of metal.

In case the sleeve should become Worn it is obvious that the position of the saine may be inverted or that a new sleeve may be substituted for said worn sleeve Without in any manner affecting the axle.

Owing to the formation of the recess g2 in the cap-flange I am enabled not only to partially embrace the outer end of the sleeve portion c, but to employ the packing-ring or gasket h for the purpose of preventing any tendency of dust or dirt passing between the cap and hub.

From the construction of my improved wheel it is obvious that the same may be produced at a reasonable cost of manufacture and that it will be of great utility on mine or other cars.

In case it should be deemed desirable it is evident that the sleeve may be removed and the round aXle allowed to bear Within the central hub portion.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

In a car-wheel the combin ation with the wheel-body, the wheel-hub consisting of the internal bearing-cylinder b and external cylinder c formed therewith, there being a continuous recess L formed in the inner wall of said inner hub portion and openings d connecting said internal recess and the oil-chamber between said hub portions, of a sleeve fitting and turning within said inner hub portion and an axle extending within and having a detachable connection with said sleeve, a hub-cap g having a peripheral flange g', said flange having a continuous recess on its inner side, a packingring h adapted to iit in said cap-flange recess, and means for uniting said cap-flange with said wheel substantially as and for the purpose specified.
